Information, contacts and swimmers' stories about swimming in the Tsugaru Channel between Honshu, the main island of Japan, and Hokkaido, an 18K strait of fast-moving currents and abundant marine life and one of the Oceans Seven channels

In October 2017, the South African attempted a crossing of the Tsugaru Channel in a tandem swim with Steve Walker. But was thwarted by the cold conditions in the latest Tsugaru Channel attempt in history.

As Cameron gets closer and closer to Hokkaido in the north, the geological contours of the curving shoreline can cause huge, powerful eddies and Cameron will feel strong upwellings of much cold water," says Steven Munatones.

"The Tsugaru Current may also start getting faster and may push him towards the middle of the channel instead of closer towards the Hokkaido shore. It all depends on the winds.

So every kilometer, every hour, Cameron will face tougher, colder and rougher conditions. But so far his pace is excellent and the conditions are not abnormally difficult. His chances look excellent."
